Video Demos and Reviews

Please note that the following reviews and videos were produced with and in relation to the VAF-7D, rather than the VAF-TXi, because the corresponding materials specific to the VAF-TXi have not yet been generated at this point in time. However, because the 7D and Rebel HDSLRs share a common image sensor, and furthermore because the VAF-7D and VAF-TXi have very similar optical performance, the VAF-7D materials are largely representative of what can be achieved with the VAF-TXi. Additional resources specific to the VAF-TXi will be published here as they become available.

Director / Cinematographer Glenn Przyborski (Przyborski Productions, Inc.) has used the VAF-7D to produce the following video (direct link at http://vimeo.com/46975139) of the interior of a submarine with the 7D. This available-light demo nicely illustrates the performance of the VAF-7D when imaging highly-detailed subject matter at large apertures:

Please view the above video at full HD 1080p resolution; as the severe effects of color aliasing and moiré are much more pronounced in video than in still images. Nevertheless, purely for convenience here, the following (downsampled) frames extracted from the video, give a concise impression of the effect of the VAF-7D:

First, a fabric lens case, as normally imaged by the 7D in 1080p - showing pronounced colored banding as a result of aliasing:

Next, the same lens case, imaged under exactly the same conditions, however using the VAF-7D - with the colored banding and moiré very successfully corrected:
